These two many-body problems are then treated differently: the electron problem in the Hartree-Fock approximation leading to single electron states and specifically to band structure for crystals; the atomic dynamics of crystals as collective excitations which when quantized lead to ph

Backup Policies for a Database System,erize the elastic medium, consisting of a line of atoms harmonically vibrating around a stahle equilibrium configuration. Second, the equation of motion of an elastic disturbance along the chain is obtained in the classical limit (d’Alembert equation) and the solution corresponding to a single elast

U. Kreimeier,Zh. Yang,K. Messmerariton dispersion relation and damping. Measurements of bulk polaritons by light scattering and nonlinear optical processes are reviewed. The linear response theory is extended to a dielectric medium with a flat surface, thus providing the surface polariton dispersion relation and damping. Measureme
